Application filed July 24, 3.9M. Serial No. @$0,052.

To all whom it may concern: l

Be it .known that l, HENRY N. Gonne, a citizen of the United V.States of America, residing in the city of St. Louis and State have invented certain new and useful Improvements in Junction Devices for Paper Boxes, of which the following is a full, clear,and exact description, reference being had to the accompanying drawings, `forming part of this specification.

My invention relates to va junctionde ce for securing the parts of paper boxes to each other, the device being more particularly intended for use in joining parts oi" folding paper boxes when they are set up yfor use. It, is especially useful in connect- I' in'g the flanges of paper su-res, .thereby permittingtransportation of IleI'.

flat condition andthe connection ofthe flanges just` prev ious to' the covers being placed in service in boxes of which they form parts.

.Figure-I is a perspectivevieuT of' a tragment of a box, including the cover therefor, the cover being equipped with my junction device. Fig. Il, is an enlarged cross section throu h a corner of the/'box closure shown in Fig. and thejunction device on suchv cor- Fig. 1H@ is an inverted view of a corner of the box closure and one ot' the junction devices With its parts nii-connected. Fig. lV is a vieiv similar to Fig. lll, with the parts of the junction device un-con nected.

Inthe accompanying drawings: A nates a box closure provided with toldable flange Wings a. The junction devices to Which my present invention pertains are utilized to join, the flanged Wings at the corners of the closure body. Each junction device comprises'tvvo sheet met-al members B and G, one of which is suitably attached `to a flange Wing L adjacent an endlthereof, and the other of which is suitably attached to another flange Wing atv anangle to the first mentioned. l

The junction device Bcomprises a body port-ion, preferably provided with tangs l by which the body of the member B may be secured to the part it is attached to. At the outer end of the junction device member B is a return iiange 2, that lies parallel with the body o said member and nates in a rear free edge 3 having utility be hereinafter fully specified. in the 'foid reifen @mee Specification of Letters Patent.

at the forward end of the member B is an aperture i through which an element carried by the junction device member .C may be inserted, as will hereinafter appear. v'

The junction device member C has a body preferably provided With'tangsI 5 that `may belinserted through a ange Wing to which the member C is applied. At the forward end of the member C is a tongue 6 provided with a supplemental spring tongue 7 that. extends backyvardly and laterally from its end nearest the i'ree end of the tongue 6 toward the body of the member C.

i ln 'the practical use of my junction device, the members B and C are applied to the parts ot the box that are to be joined there'- by, and to eiect the connection of such parts, 'it is only necessary yto insert the main tongue 6 and supplemental spring tongue 7 through the aperfure e in the member B and move them between the 'body of the member B and its return iange 2 until the free end of the supplemental spring tongue passes beyond the rear free edge 3 of the return ange. rihe spring tongue, on being relieved of pressure, springs outwardly away from the main tongue (S and then when said main tongue is moved baclrwardly, to a slight degrec. the free edge of the return bend 2 is straddled by the main tongue and spring= tongue, 'thus proyidingloclring engagementbetween the junction' member and the junction member Figs. il and lV.

it will be readily .appreciated that the main tongue 6 ot the junction member C may be readily bent at an angle to the body of the member. This being true, it is possible to apply the member C to box closure iange Wings, with the main tongues in alinement with the body of the closure, so that they are parallel WithI the box closure iange Wingsjvvhen'in` fiat condition. Then, when the iiange Wings are to be connected, the main tongues 6 are readily bent at angles to the bodies of the members C to permit of their being placed in interlocking engagementfWit-h the junction members B after the been folded. `While l have in vthe preceding description set forth my junction device as utilized to connect the flange Wings of box closures, wish it understood that l do not limit myself to the use of the device in connecting such flange Wings, as it is obvious the de- B, as most clearly seen in vice may be used to connect other parts of paper boxes and'that in such use itmay be employed, irrespective of Whether or not the parts connected` are at angles to each other, or in alinement with or parallel to each other.

Having thus described my invention the following is what I claim as new tbereinv and desire to secure by Letters Patent: In a device of the cbaracter described, a Junction member comprising a body portion -and atinain tonguei the main tongue being provided with a supplemental spring tongue extending backwardly toward said body portion; and a second junction member comprising a body portion and return {ia-nge parallel with said body portionterminating in a` free rear edge, the joining fold at the forward end of said return flange being` apertured to receive said main tongue and supplemental tongue of the first named junction member, and the free rear edge of said return flange being4 separated from the body portion of the second junction member permitting the straddling interlockingr` engagement therewith of said main and supplemental tongues.
